Hi all,

Let me just step in to this discussion, not replying to any post in particular. From a plain user point of view, we sometimes get source code with a Makefile and compile it. We trust the configuration scripts and the "default" options provided, and we not always read thoroughly all documentation of all flags that may have been set in tons of different configuration files. I'm not saying that the compiler should always do the "right thing", but sometimes it's not that users don't want to read the documentantion, it's just that we don't expect to be required to do so.

That said, why not issue a warning when -malign-double is used, just as the warnings issued when an option does not exist or is not applicable to the current architecture? That way, the user can know that a potentially problematic flag is being used, and if someone really wants to use it, they could maybe deactivate the warning with -Wno-malign-double or something similar. Does this make sense?

Ignacio
